Optical Expansion System
We offer on request an expanding optics for the interferometer VI direct 100 to extend the free aperture from 100 mm to 150 mm. Thus, specimens with a diameter of up to 150 mm can be examined. The expander optics can be used e.g. with the reference plate D 150.
Note: The expander optics is specially designed for the interferometer VI direct 100 and any other use is not recommended.
